Present study deals with the individual and combined effect of Glomus fasciculatum and indigenous Glomus mosseae isolate on growth and nutrient contents of Arachis hypogaea under soil salinity stress (EC: 1.04, 2.10, 3.78, 5.94 and 8.26dS/m). After growth period of sixty days, a significant improvement in plant height, dry biomass, total chlorophyll, proline content was observed in mycorrhizal plants over non mycorrhizal plants. Mycorrhizal plants inoculated with both the isolates in combination showed a maximum increment in the parameters like dry biomass (29.46%), total chlorophyll (28.45%), proline (16.66%), soluble protein (23.35%), soluble sugar content (30.63%) and mycorrhizal dependency (22.76%) at provided salinity stress levels. Reduction in electrolyte leakage in mycorrhizal plants may help to overcome adverse salt effects on plant growth. G. mosseae and G. fasciculatum isolates in combination can be used as bio-inoculant to alleviate negative salinity effect on A. hypogaea plant growth and nutrient accumulation.
